I recently acquired this 486 VLB motherboard, it looks to be in pretty good condition. Has a Cx486 DX2V66, and battery hasn't leaked at all.

There is a model number between the ISA slots says 29GDX4-11B, but it doesn't lead to anything on Google at all. Does anyone here have a bit more information about this MB? I do want to make sure all the jumper settings are correct before powering it on. Thanks.

Does this card posts?Maybe post code will identify manufacturer of board.
Also cache seems fake, i may be mistaken.
Cipset seems ALI but there is 5v-3v sticker i am also not sure.
Edit:Nevermind you never powered board.

I think I've found it http://www.win3x.org/uh19/motherboard/show/5545

Manufacturer is still unknown, but the schema seems accurate.

As said, a screenshot of the POST screen would be useful to fully identify the board. A BIOS dump would be even better (if your board does boot, use this to dump it http://cd.textfiles.com/microhaus/mhblackbox3 … MORY/GETROM.ZIP)

Nice catch !
Another board that gets a clear photo attached 😀

edit, seems like some jumpers are indeed not correctly set... cpu voltage for one.

Right to repair is fundamental. You own it, you're allowed to fix it.

Your board also has fake cache (the chips are soldered, this is typical for boards with fake cache).

Could you please peel off that sticker on the chipset so we can identify it ? 😀

Here it is! Looks like an ALI M1429G indeed. Well spotted!
